Zusammenfassung:A method is disclosed for producing a multicoat paint system on a metallic substrate by producing a basecoat or a plurality of directly successive basecoats directly on a metallic substrate coated with a cured electrocoat system, producing a clearcoat directly on the one or the topmost of the plurality of basecoats, and subsequently jointly curing the one or the plurality of basecoats and the clearcoat. At least one basecoat material used for producing the basecoats includes at least one predispersed mixture including at least one polyamide having an acid number of less than 20 mg KOH/g, at least one polymeric resin different from the polyamide, and also water and at least one organic solvent.
